Blob Storage Core Concepts

The core concept of Azure Blob Storage revolves around three key elements:

1. Blobs: Blobs are the individual units of data stored in Blob Storage. They can be of varying sizes, ranging from a few bytes to several terabytes. Blobs are typically used to store large files or chunks of data that don’t fit well in traditional databases.

2. Containers: Containers are logical storage entities within Blob Storage that act as a way to organize and categorize blobs. You can think of containers as top-level directories that hold related blobs. Containers provide a level of organization and help manage access control and permissions for the blobs within them.

3. Storage Accounts: Storage accounts are the foundational entities in Blob Storage. They serve as the entry point for creating and managing blobs and containers. A storage account provides unique credentials and endpoint URLs that allow you to access your Blob Storage resources securely.

Blob Storage Core Concepts

Blob Storage vs. Traditional File Storage

Blob Storage differs from traditional file storage systems in its approach to data organization and management. In traditional file storage, data is stored in a hierarchical structure of directories and files, mirroring the familiar file system structure on your computer.

On the other hand, Blob Storage does not enforce such a structure. Instead, it allows you to organize data using containers, providing a flat namespace. This flexibility means that you can store blobs directly within containers without the need for a specific directory hierarchy.

This distinction is particularly useful when dealing with unstructured data that doesn’t fit neatly into a traditional file system structure. Blob Storage allows you to manage and access files with varying formats, properties, and metadata more efficiently.
